As usual with most Game Boy Advance titles, Nintendo is the only one
who published an official player's guide for MZM. But also as usual, Nintendo's guide is
slick, cleanly laid-out, easy to understand, and very helpful, with
each point in the game explained as well as a guide to all the endings.
And like their Prime guide, it contains a complete guide to the unlockable NES Metroid.
But wait, there's more -- possibly as a nod to all the hardcore Metroid fans
of the Internet who revel in the challenge of completing the game with
as few items as possible, N has even included a "15% Walkthrough,"
showing how to finish MZM with only 15% of the items.
